There are a few ways to do this. I can think of two just off the top of my
head.

If you wanted to go that route, you could create your own item delegate and
draw the items yourself.

Probably the easiest place to start is to swap out the view used to display
the combo box's pop-up menu. I've put some sample code up on the PyQt Wiki:

It's also linked to from the SampleCode page:

There are limitations with this approach, but it may be just enough to do
what you want.
